The crystallization behaviour, the lattice parameters of the crystallized phase and the crystallization kinetics of amorphous Fe73.5Cu1Nb3Si13.5B9alloy were investigated by X-ray diffraction and differential scanning calorimetry. When the alloy was annealed at above 480°C for 1 h, nanocrystalline Fe(Si) phase precipitated from the amorphous matrix. As the annealing temperature rose, the lattice parameter a0of the Fe(Si) phase increased from 0.2838 nm to 0.2849 nm. At 600°C tetragonal Fe3B precipitated, and at 670°C f.c.c. Fe23B6. After pre-annealing above 400°C, the crystallization activation energy was raised significantly from 384 kJ Mol-1to 494 kJ mol-1. During isothermal annealing the crystallization activation energy dropped from 520 kJ mol-1to 360 kJ mol-1as the annealing continued, while it increased appreciably with pre-annealing. © 1995.
